Use an open port scanner to understand network configurations

Open Port Scanner - Scan and Test Open Ports 0 Features Array Item - features item image

Advanced port checkers can help provide insights into how your devices are configured. SolarWinds® Engineer's Toolset™ (ETS) is designed to help you more easily understand whether your network and ports are using appropriate settings.

Using ETS, you can run scans to gain insight into how routers, hubs switches, and other devices are configured by analyzing SNMP queries and viewing MIB attributes. ETS also uses threading and adaptive timing to help shorten scan run times. You can even save scan configurations to quickly recall them later.

Leverage an open port checker to gain a useful list of port statuses

Config Compare Tool - Configuration Management - Main Page Content Image 1

Use SolarWinds ETS open port checker tools to gain a list of open, closed, and filtered ports across your IP addresses. You can also sweep IP ranges and identify devices and TCP and UDP services. This can help you see which devices are connected to your network and what services are accessible.

With an open port checker, you can gain visibility into port statuses then easily export and report on the results. The dashboard in ETS can provide visibility into and help you more easily manage configurations for network routers and switches.

It’s important to test open ports to ensure they can be used by applications—and they’re not posing a security risk.

SolarWinds ETS offers open port scanner capabilities using SNMP MIB browser, which is designed to give you insight into the network by enabling you to query SNMP-managed devices. You can also use the Neighbor Map and Route Viewer tools in ETS for a visible overview of how your network is routing.

Ensure you have a tool for security-related open ports scanning use cases

Open Port Scanner - Scan and Test Open Ports 3 Features Array Item - features item image

For port scanning, addressing the risks posed by open ports is a common use case. Visibility into your network’s organization and usage can help you more quickly troubleshoot risks to better protect your infrastructure.

With Engineer’s Toolset open port scanner software, you can discover your network components, map switch ports, and gain optimal visibility into endpoint devices. If open ports exist, you’ll have the data to help ensure they remain secure.

Gain more complete network recon

Open Port Scanner - Scan and Test Open Ports 4 Features Array Item - features item image

ETS has a Network Sonar tool that can inventory your network and ports, including SNMP-managed devices. You can also use the MAC Address Scanner, DHCP Scope Monitor, and DNS Analyzer tools in SolarWinds ETS to better understand how IP addresses are being assigned and resolved. Additionally, the Switch Port Mapper in ETS can show you what devices (hostname, IP, and MAC address) are connected to your switches.

Get More on Open Port Scanner

Do you find yourself asking…

  • What is a port?
  • What is an open port?
  • How can I see what ports are open on my network?
  • What is an open port scanning tool?
  • How does an open port scanner work?
  • What are the benefits of open port scanning?
  • How does the open port scanner work in Engineer’s Toolset?

A port is a communication endpoint where information is sent and received. Ports are part of how computers can connect to networks. Webpages rely on ports to be accessible to clients. Ports vary in their protocols and the types of services they offer. The most common protocols for ports are transmission control protocol (TCP) and user datagram protocol (UDP).

Open ports are “open” to remote communication. They designate TCP and UDP port numbers configured to accept packets. A port rejecting connections and packets is “closed.”

Open ports are necessary for apps to function and for clients to access your server.

You can conduct a port scan to see what ports are open on your network. Port scans work by sending client requests to a range of hosts to determine which ports are active. This simply tells you if the ports are active and determines whether its services are available to a remote device.

An open port scanner tool is designed to scan a server or a host for open ports. These tools are used to scan for vulnerabilities, because open ports can act as security holes attackers may exploit.

Port scanners test open ports and display the ones open for communication. They determine this by sending client requests to ports on a host (an IP or URL).

All port scanners make certain basic assumptions, but they can work in different ways and vary in terms of complexity. Some open port scanners only scan the most common port numbers or ports likely to have vulnerabilities. This depends on the scanner you’re using and your customized preferences.

Common port scan types include:

  • A TCP port scan is a technique to test open ports for common port numbers. It doesn’t test IP ranges or all 63535 ports. TCP port scans will show whether a firewall is present and blocking traffic to certain ports.
  • Ping scans can sweep network blocks to check if targets are responsive. A ping scan sends client requests to the target to generate a response.
  • UDP scanning is a connectionless protocol commonly used to detect DNS, SNMP, and DHCP services. If a UDP packet reaches a closed port, the system responds with an “unreachable” ICMP message.

Using an IP port open scanner can help reveal vulnerabilities attackers can potentially exploit and allow you to better understand how your network is routing. Port scans are also an important part of conducting penetration tests, such as simulating SNMP brute force attacks. Generally, firewalls and security protocols can be configured to protect ports and block traffic from attacks.

The open port scanner features in Engineer's Toolset are built to offer comprehensive functions to help you scan for devices and secure, troubleshoot, and document your network.

Using a port scanner to check for open ports is important but running the tool alone may not be enough to secure your network. Engineer’s Toolset is designed to combine port scanning with a host of other functions to help give you a complete picture of your network with 60-plus tools included.
